Discriminated protection-message body, selected by table_id_extension.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AuthenticationMessage

Authentication message (extension 0x0000..=0x00FF; §9.4.3 Table 42).

Fields

section_hash_algorithm_identifier: u8

section_hash_algorithm_identifier (§9.4.3 Table 43): 0 = SHA-256, 1 = SHA-512.

section_hash_length: u8

section_hash_length — bytes per hash in each loop entry.

signature_algorithm_identifier: u8

signature_algorithm_identifier (§9.4.3 Table 44).

hashes: Vec<SectionHashEntry<'a>>

Section-hash loop entries in wire order.

extension_bytes: &'a [u8]

extension_byte payload (length-prefixed by extension_bytes_length).

signature_key_identifier: &'a [u8]

signature_key_identifier_byte payload (length-prefixed).

signature: &'a [u8]

Detached signature — runs from after the key identifier to the CRC.

reserved_section_hashes_loop_length: u8

reserved(4) before section_hashes_loop_length (1111); preserved from the wire.

CertificateCollection

Certificate collection message (extension 0x0100; §9.5.4.9 Table 51).

Fields

certificates: Vec<&'a [u8]>

DER-encoded DVBCertificate byte runs, one slice per certificate_length loop entry.

reserved_certificate_count: u8

reserved(4) before certificate_count (1111); preserved from the wire.

reserved_certificate_lengths: Vec<u8>

reserved(4) before each certificate_length (1111), parallel to certificates; entries missing from the vector default to all-ones on serialize. Preserved from the wire.

Raw(&'a [u8])

Reserved extension (0x0101..=0xFFFF) — body preserved verbatim.
